Donald Trump -- Would You Buy a Used Car from this Man?

Donald Trump has the Midas touch ... a car he bought for a famous ex-wife nearly a quarter century ago just sold for thousands of dollars above the original sticker price.

It's a 1991 Acura NSX Trump bought for Marla Maples, who looked hot posing next to it back in the day. Purchase price: $35k. She unloaded it in 2005 to Mark Dobkin for the original price.

Mark's a clever guy ... he put the car up for sale on eBay recently, and made it crystal clear it has a Trump/Maples pedigree.

His marketing worked fantastically ... the car fetched $48,000. Mind you, the Kelly Blue Book values the car at $20k.

When you think about it, Mark isn't a Trump believer, because if he held the car until late January 2017, think about what it could be worth.
